The first unit ordered failed within one month but luckily Amazon fixed that problem for me and sent another. The one they sent worked for 1yr and now it had a melt down. Found a loose wire on a sensor causing a lot of heat and burned the unit up. This wire was supposed to be tightened at the manufacturer and not part of the install.

Also you might want to consider getting a unit with a temperature regulator because water comes out at largly different temperatures from the summer to the winter based on underground water temperature.

This product is perfect for homes where the space is an issue or for locations distant from heating source.
The first heater we received and installed was mullfunctioning. After discussing the troubleshooting with BOSH, Amazon the same day we contacted them sent us new replacement. Returning the first heater could be easier. Thank you Amazon.com!
My electric panel was just some year new, we did not have to provide any additional works besides wiring the heater. I saved all closet space(where I had located 30gal. el water heater) for other use. Heater is very small, it would easily fit under the sink. Temperature of hot water can be adjusted to your needs. 2 gallons of hot water per minute are good enough. According to professional installer, the heater is so simple device, that it should not have any additional problems.
I am very happy with the product and am starting considering this type of hot water heater for whole house, no matter price for electrical works.
Where the space is an issue, this product is one of great solutions.
I am highly recommending this heater.
Forgot to mention: Saving for electricity was instant.
2 years later it still works great.

This thing works for me! It is the main (only) domestic HW heater for a 1 1/2 bath house, with laundry. Be aware of the electrical requirements before ordering - the 50 amp. line is heavy stuff, and not like running a 14-2 line. For safe installation, do not use the 10 ga. electric line that ran your old electric heater - it's too small. I also had to install an electric shut-off by the unit, per its instructions, which wasn't expected.

I changed my showerhead to a 1.5 gpm flow design (WaterPik eco-flo)to boost the efficiency of the unit. The 2.5 gpm that was replaced could overtax the unit. If you don't have a 'scaldguard' shower valve installed, you may not need to replace the showerhead, but with one, the shower is either all the way on, or all the way off.

It took some tinkering to get the flow and thermostat set where I wanted, but once that was done, it works very well. I don't believe one of the non-thermostatic units would have worked for me.

The internal reset switch needed to be reset once, and killing the power at the breaker, the shutoff, and getting the plastic housing off the unit, finding and resetting the switch, and then reversing the above was a pain. BUT it has only needed to be done once so far.

The extra storage space in the tiny utility room was unbelievable.
